Answer:

To figure out the total measure of the angles for a 27-gon, there is a formula.

n - 2 x 180* (n is the number of sides, which would be 27)

27 - 2 = 25

25 x 180* = 4500*

The total measure of the angles of a 27-gon is: 4500*

EXPERTS ONLY its not 0 or 128 In how many ways can you put seven marbles in different colors into four jars? Note that the jars

KonstantinChe [14]

Answer: 16384

Step-by-step explanation:

Given, Total jars = 4

Total marbles = 7

Since we need to put marbles in 4 different jars, we need to choose a jar each time.

Possible choices for jars =4

Number of time we need to choose = number of marbles

So, by fundamental counting principle, we have

Total ways to put 7 marbles in 4 jars = $4\times4\times 4\times 4\times4\times 4\times 4$

$=4^7\\\\=16384$

Hence, the required number of ways =16384

Which of the following sets of points are vertices of a right triangle?

grandymaker [24]

Please find the picture for your triangle.
We know, area of a ∆ = 1/2 × base × height
Here, base = ( 1 + 7 ) units = 8 units
Height = ( 7 - 1 ) units = 6 units
Therefore, area of the ∆
= (1/2 × 8 × 6) square units
= 24 square units.

Answer:

24 square units

Hope you can get an idea from it.

Carry on learning.

"A passenger train traveled 100 miles in the same amount of time it took a freight train to travel 90 miles. The rate of the fre

Pavel [41]

Answer: the rate of the passenger train is 100 mph.

Step-by-step explanation:

Let x represent the rate of the passenger train.

The rate of the freight train was 10 miles per hour slower than the rate of the passenger train. It means that the rate of the freight train is (x - 10) mph

The passenger train traveled 100 miles. It means that the time it took travel 100 miles is

100/x

In the same amount of time, it took a freight train to travel 90 miles. It means that the time it took travel 90 miles is

90/(x - 10)

Since the time is the same, then

100/x = 90/(x - 10)

Cross multiplying, it becomes

100(x - 10) = 90x

100x - 1000 = 90x

100x - 90x = 1000

10x = 1000

x = 100 mph

Write an equation of the line that passes through (2,-5) and is parallel to the line 2y = 3x + 10

Diano4ka-milaya [45]

Answer:

y=3x/2 -8

Step-by-step explanation:

2y/2 = 3x/2 + 10/2

y = 3x/2 +5

(y-(-5)) = 3/2 (x-2)

y+5 = 3x/2 - 3

y= 3x/2 - 8
